赛博物理系统研究与发展综述

Review on Cyber-Physical System Research and Development

赛博物理系统(CPS, Cyber-Physical System)是一个包含计算、网络和物理实体的复杂系统,被誉为下一代网络技术。本文详细介绍了CPS的定义与特点,回顾了CPS的起源及国内外发展历程。通过与现有的嵌入式系统、网络控制系统、物联网、工业控制系统等技术的对比,讨论可用于CPS的现有理论和技术,重点分析了CPS设计中的安全性、可靠性和可信性。立足于智慧交通、智能电网、智慧医疗等CPS典型应用,在总结已有研究成果的基础上,指出现有典型应用所存在的问题与挑战,展望了CPS系统的研究动向。

Cyber physical system (CPS) is a complex system including computing, network and physical enti-ties, known as the next generation network technology. This paper introduces the definition and characteristics of CPS in detail, and reviews the origin and development of CPS at home and abroad. Starting from the existing embedded system, network control system, Internet of things, and industrial control system, the paper discusses the existing theory and technology that can be used in CPS, and focuses on the analysis of the safety, reliability and credibility in the design of CPS. Based on the typical application of CPS such as intelligent transportation, intelligent power grid and intelligent medical treatment, and on the basis of summarizing the existing research results, this paper analyzes the key technologies of application-oriented CPS, points out the problems and chal-lenges existing in the typical application, and looks forward to the research trend of CPS system.
